RESUMEN

Ovarian cysts develop rarely in fetuses during pregnancy and usually disappear after birth. However, during pregnancy, torsion and rupture of the cyst can occur and it is necessary to manage such cases. At present, there is no standardized prenatal or neonatal treatment. However, the preservation of ovarian function is an important consideration. Here, we present a case involving a 35-year-old woman who gave birth to an infant with a complicated ovarian cyst, which was resolved through laparoscopic surgery on the third day after birth. The prenatal diagnosis of the fetal ovarian cyst was performed prenatally using ultrasound and magnetic resonance imaging (MRI). However, torsion of the ovarian pedicle was suspected because of dorsal thickening of the cyst wall and fluid formation indicated by high intensity on T1- and T2-weighted MRI. Surgery was complicated due to involvement in the torqued pedicle of the left fallopian tubal fimbria, which was released. The cyst was drained and partially resected, and then the pedicle torsion was released. By four years and five months of follow-up, there had been no ovarian cyst findings on ultrasound or MRI. Larger cysts are more likely to involve torsion of the ovarian pedicle and potential bleeding. Considering that, in this case, the cyst was large and proved to be ischemic-hemorrhagic, the decision to operate seemed justified.

RESUMEN

Sigmoid volvulus requires urgent treatment, and it is particularly rare among pregnant women without a history of laparotomy. A delay in diagnosis may lead to serious consequences for the mother and fetus, and a rapid diagnosis and treatment in this setting is essential. The patient was a 19-year-old primiparous woman. She complained of repeated exacerbations and remissions of abrupt lower abdominal pain for the past 2 days and was transported to our hospital at 33 weeks of gestation. Ultrasonography revealed no placental thickening, and maternal bowel dilation was difficult to identify. Plain abdominal X-ray showed a dilated colon on the left side of the abdomen. Contrast-enhanced CT scan of the abdomen revealed a volvulus on the dorsal side of the uterus. The proximal end of the transverse to sigmoid colon was markedly dilated, and the distal end was collapsed. The elevated lactate level on blood gas analysis suggested intestinal ischemia. She was suspected of having a sigmoid volvulus at 33 weeks and 3 days of gestation. We decided to perform a cesarean section to secure the operative field for an intestinal resection following delivery. A male weighing 1840 g with Apgar scores 8/8 was delivered. The sigmoid colon was approximately 80 cm in length. A 360-degree clockwise rotation of was observed with a very distended but viable sigmoid loop. Following reduction of the volvulus, the sigmoid colon was fixed to the left side of the peritoneum. The mother had an uneventful postoperative course, and the infant was discharged without any sequelae. This case demonstrates two important lessons. First, sigmoid volvulus can occur in pregnant women even if they never had a laparotomy. Second, abdominal contrast-enhanced CT is useful for rapid diagnostic and treatment decisions relative to this pathology.

RESUMEN

The case is presented of a 29-year-old primiparous woman who was COVID-19-positive at 34 weeks of gestation and who developed severe acute respiratory distress syndrome. After a four-day history of fever and mild dyspnea, she was referred to hospital. Ciclesonide, dexamethasone, heparin sodium, and sulbactam/ampicillin were initiated, followed by remdesivir and tocilizumab. On the fourth day after admission (at 34 weeks 5 days of gestation), respiratory failure required ventilator management. An emergency cesarean section was performed and a 2565-g male infant was delivered with an Apgar score of 8/8 and negative COVID-19 status. However, on the following day the patient's respiratory condition deteriorated and mechanical ventilation was initiated. Subsequently, her respiratory condition quickly improved and mechanical ventilation was terminated 4 days after intubation. She was discharged 12 days after cesarean delivery. Our case provides additional evidence that raises concerns regarding the unfavorable maternal consequences of COVID-19 infection during pregnancy.

RESUMEN

OBJECTIVES: Neonates delivered by women who were taking psychotropic or anticonvulsant drugs during pregnancy are at increased risk of developing neonatal withdrawal syndrome. We investigated the incidence of neonatal withdrawal symptoms and the effects of multiple maternal medications and breastfeeding on neonatal withdrawal symptoms. STUDY DESIGN: This study examined the overall incidence of neonatal withdrawal symptoms in neonates delivered from 2004 to 2016 by women who were taking oral antipsychotics, antidepressants, anxiolytics, sedatives, or anticonvulsant drugs during pregnancy. Moreover, we compared the incidence of neonatal symptoms between mothers taking single drugs and multiple drugs, and between breastfed and formula-fed neonates. We scored the neonates according to the neonatal withdrawal syndrome checklist created by Isobe et al., which is widely used in Japan. RESULTS: We examined 131 mothers and their 134 neonates. Withdrawal symptoms were found in 54.5 % of neonates. Symptoms were found in 32.4 % of neonates delivered by mothers taking single drugs and 62.9 % of neonates delivered by mothers taking two or more drugs (p = 0.0019). One or more withdrawal symptoms developed in 46.4 % of breastfed neonates and 66.1 % of formula-fed neonates (p = 0.034). Five infants had a score of 8 or more points on the withdrawal checklist, which is an indication to consider treatment with pharmacotherapy. All five of these neonates were mainly formula-fed, and their mothers were taking two or more drugs. CONCLUSIONS: The incidence of withdrawal symptoms was high in neonates delivered by women taking psychotropic or anticonvulsant drugs; however, there were few serious cases. The risk increased when a mother was taking multiple drugs. Breastfeeding appeared to protect against withdrawal symptoms.

RESUMEN

Pseudoaneurysms generally develop when an arterial puncture site is inadequately sealed. We encountered a case of vaginal pseudoaneurysm that developed 3 years after cesarean section in a 35-year-old gravida 7 para 4 woman who was prescribed with anticoagulant and antiplatelet drugs after surgeries for ventricular septal defect and aortic valve replacement. Pelvic computed tomography scan revealed a large mass, which showed a dappled contrast filling on the arterial phase, located in the posterior vaginal wall. The vaginal pseudoaneurysm was completely occluded by embolization of the left vaginal artery. Anticoagulation and antiplatelet therapies can be potential causes of spontaneous pseudoaneurysm rupture. Extrauterine pseudoaneurysm has a long period of time between cesarean section and pseudoaneurysm discovery. Considering that pseudoaneurysm shows different clinical features for each patient, we should always consider pseudoaneurysm when we assess a patient with postpartum hemorrhage.

RESUMEN

Massive subchorionic thrombohematoma (MST), termed Breus' mole, is a rare condition in which a large maternal blood clot separates the chorionic plate from the villous chorion. Common complications of MST include fetal growth restriction, preeclampsia, and intrauterine fetal death. Here, we present a case of a 17-year-old Japanese woman referred to our institution at 21 weeks of gestation. Ultrasound examination revealed a large placental mass with mixed high and low echogenicity measuring approximately 7.6 cm in thickness. Doppler examination showed absence of end-diastolic velocity of the umbilical artery. At 22 weeks of gestation, the patient had a stillbirth weighing 138g. The placenta weighed 502 g and was 8 cm thick, and the total blood loss was 270 g. Macroscopic examination revealed that a subchorionic blood clot measuring 12 cm × 5 cm covered a large portion of the placenta with well-defined margins on the fetal surface. Microscopic examination revealed an intervillous hematoma and fibrinous deposits directly beneath the chorionic plate with adjacent compressive effects. Based on these findings, MST was diagnosed. Because MST is rare, it must be considered in the differential diagnosis of parental conditions. Magnetic resonance imaging can be optimal for diagnosing MST when ultrasound diagnosis is difficult.

RESUMEN

We report a case of Cornelia de Lange syndrome (CdLS) where prenatal diagnosis was not made even with major anomaly. A 33-year-old Japanese woman was referred to our institution at 23 weeks of gestation because of fetal forearm defect. Ultrasound examination revealed short forearms and short humeri and femurs (-2.1 SD). The fetal estimated body weight was 450 g (-1.3 SD). Fetal MRI at 26 weeks of gestation revealed short forearms and hypoplasty of hand fingers. Fetal growth restriction became evident thereafter, leading to intrauterine fetal death occurring at 29 weeks of gestation. A stillbirth baby was of 798 g in body weight and 33.0 cm in length. External examination showed a low hairline, synophrys, low-set ear, hypertrichosis, and smooth long philtrum with thin lips. The neck appeared short and broad. Finally, CdLS was diagnosed. The prenatal diagnosis might be possible as the arm findings were totally characteristic in a small fetus, regardless of whether an overhanging upper lip was identified. Because CdLS is a rare condition, it is important to consider its possibility as a part of differential diagnosis.

RESUMEN

A 37-year-old (G4P3) woman was referred to our hospital at 32 weeks of gestation for the evaluation of a fetus with an intrathoracic cystic lesion. Ultrasonography and magnetic resonance imaging revealed that a fetal cystic lesion without a mucosal layer was located in the posterior mediastinum. These findings were consistent with a bronchogenic cyst. At 38 3/7 weeks of gestation, an elective cesarean section was performed because of her previous cesarean section. A female neonate without any external anomalies, weighing 2,442 g, with Apgar scores of 8 and 9, and requiring no resuscitation was born. Four weeks after delivery, the neonate was admitted because of respiratory distress due to mass effect. At right lateral thoracotomy, a 105 × 65 mm of solitary smooth-walled cyst containing serosanguineous fluid was found in the posterior mediastinum, which was excised completely. Histologic examination revealed the diagnosis of the mediastinal gastric duplication cyst. The neonate made an uneventful recovery. Accurate diagnosis is not necessary, but detection and continuous observation are logical. Although gastric duplication, particularly intrathoracic, is a rare pathology, it should be considered in the differential diagnosis of any intrathoracic cyst.

RESUMEN

Two types of congenital bronchial atresia (proximal and peripheral) have been classified. We report two cases of peripheral bronchial atresia diagnosed by prenatal ultrasonography (US) and magnetic resonance imaging (MRI). Evaluating an enlarged lung mass that is homogeneously hyperechoic on US and hyperintense on T2-weighted MRI can help in determining whether bronchial atresia is present. Proximal type is suggested when a dilated main bronchus is observed as a tubule structure of an involved lung hilum. In our cases, T2-weighted MRI revealed homogeneously hyperintense lung lesion with decreased signal intensity of adjacent lobe, flattening diaphragm, and mediastinal shift. Dilatation of the main bronchus was not observed and the opposite lung was normal in appearance. These findings were explained by secondary compression due to enlargement of the involved lung. The preservation of vascular structure and the retained normal shape, though enlarged, in the affected lobe were observed, which demonstrated undisrupted pulmonary architecture of the lobe. Thus, congenital cystic adenomatoid malformation was excluded because pulmonary architecture was relatively preserved. Finally, presumed diagnoses of the peripheral bronchial atresia were made and confirmed by postnatal chest computed tomography.

RESUMEN

A 40-year-old pregnant woman presented with a fetal abdominal cyst and oligohydramnios. Color Doppler scan revealed a single blood vessel from the fetal aorta into a single umbilical artery. Severe oligohydramnios limited ultrasonographic evaluation of the fetal lower limbs, kidneys, or bladder. The pregnancy was terminated; the fetus showed fused lower limbs, bulging abdomen, and absent external genitalia and was diagnosed with type III sirenomelia. On autopsy, no normal bladder was observed, but duodenal atresia, anorectal atresia, and right renal agenesis were found. An intra-abdominal cyst, diagnosed histologically as a saccular cloaca, occupied the abdominal cavity. Ultrasonographic diagnosis of fetal sirenomelia is difficult due to poor depiction of the lower limbs. A vitelline artery leading to a single umbilical artery and a fetal abdominal cyst occupying most of the abdominal cavity are considered fetal sirenomelia associated with large defects of the gastrointestinal and genitourinary tracts.

RESUMEN

PURPOSE: To evaluate the effect of embryo quality on pregnancy outcomes. METHODS: This retrospective analysis included 80 live singleton births, resulting from morphologically good-quality embryo transfers, and 25 live singleton births that resulted from morphologically poor-quality embryo transfers between January, 2008 and December, 2014. Cleavage embryos that were graded as ≥2, according to the Veeck classification system, and blastocysts that were graded as ≥3BB, according to the Gardner classification system, were defined as good quality. The obstetric and neonatal outcomes were compared between the poor- and good-quality embryo transfer groups. RESULTS: The mean maternal age between the groups was similar. The blastocyst transfer rate was higher in the good-quality, than in the poor-quality, embryo transfer group. Other characteristics, including parity, infertility duration, the intracytoplasmic sperm injection rate, frozen-thawed embryo transfer rate, endometrial thickness, and hormone values before the embryo transfer, were similar between the groups. The obstetric and neonatal outcomes of live births between the two groups were not different in terms of preterm delivery, birthweight, small or large size for gestational age, malformation, umbilical artery cord pH of <7.20, hypertensive disorders of pregnancy, gestational diabetes mellitus, chorioamnionitis, placenta previa, and placental abruption. CONCLUSION: The obstetric and neonatal outcomes of live births between the poor- and good-quality embryo transfers were equivalent.

RESUMEN

Aim We report a case of congenital pulmonary airway malformation (CPAM) with hydrops in which the fetus underwent thoracoamniotic shunting. Case Report A 40-year-old (G1P1) woman was diagnosed with a macrocystic CPAM. Thoracoamniotic shunting was performed at 19 weeks of gestation but not well drained and was successfully performed again at 23 weeks. However, the CPAM volume ratio, abdominal circumference, and amniotic fluid index started increasing from 28 weeks and hydrops worsened. The insufficient shunting and the fetal cardiac failure had to be considered. At 32 weeks, a male infant with general edema and massive ascites was born weighing 3,362 g (+4.79 SD) with Apgar scores of 2 and 4. The infant was intubated and high-frequency oscillation and nitric oxide therapies were instituted. The resection of CPAM was performed on day 2. Nasal continuous positive airway pressure was instituted on day 16. The infant was discharged and prescribed with home oxygen therapy (HOT) on day 65. The infant was able to leave the HOT at 30 months and is currently 34 months of age in good condition. Conclusion Fetal thoracoamniotic shunting may be life-saving in CPAM complicated by hydrops and that this treatment might be sufficient to cure the child.

RESUMEN

It was demonstrated that second- and third-trimester therapeutic termination of pregnancy (TOP) is feasible in cases with placenta previa. We report a 34-year-old woman with complex fetal malformations associated with placenta previa. An ultrasound examination at 21 weeks of gestation revealed fetal growth restriction (FGR) and complex fetal malformations associated with a placenta previa. After extensive information, the parents opted for careful observation. Thereafter, FGR gradually progressed and we observed arrest of end-diastolic velocity of the umbilical artery. Finally, intrauterine fetal death (IUFD) was confirmed at 33 weeks of gestation. Two days after IUFD, the patient experienced labor pain. The placenta and dead fetus weighing 961 g were vaginally delivered, and total bleeding was 270 mL. Although further studies to confirm the dynamic change of the uteroplacental blood flow are necessary to avoid the risk of maternal hemorrhage, vaginal TOP with placenta previa after feticide or IUFD would be feasible.

RESUMEN

Background. We experienced a rare case of a pregnant woman with Klippel-Trénaunay syndrome complicated with diffuse venous malformation of the uterus. This is the first report on the usefulness of dynamic contrast-enhanced-MRI for the diagnosis of diffuse venous malformation of the uterus. Case Presentation. A 23-year-old woman presented with convulsions and talipes equinus position of both lower limbs at 11 weeks of gestation. At 27 weeks, ultrasonography demonstrated tubular echolucent spaces throughout the myometrium. Dynamic MRI at 37 weeks revealed that the myometrial lesion was enhanced slowly and showed homogeneous enhancement even on a 10 min delayed image. Taken together with unilateral foot hypertrophy, varices, and port-wine stain, the patient was diagnosed as having Klippel-Trénaunay syndrome complicated with diffuse venous malformation of the pregnant uterus. The patient underwent elective cesarean section because of severe dystonia. The lower uterine segment was thickened and heavy venous blood flow was observed at the incision. Histological diagnosis of the myometrial biopsy specimen was venous malformation. Conclusions. Both diffuse venous malformation and Klippel-Trénaunay syndrome during pregnancy can involve considerable complications, in particular, massive bleeding during labor. Women who suffer from this syndrome should be advised about the risk of complications of pregnancy.

RESUMEN

Background. With regard to the therapy for early invasive cervical carcinoma during pregnancy, radical trachelectomy is also a treatment of choice, along with its advantages and disadvantages. Case Report. A 28-year-old woman, para 1-0-0-1, was diagnosed with FIGO stage IB1 squamous cell carcinoma of the cervix at 12 weeks of gestation. The patient underwent radical abdominal trachelectomy with pelvic lymphadenectomy at 17 weeks of gestation. Her pregnancy was successfully maintained after the surgery. The patient underwent a planned cesarean section at 38 weeks of gestation. A healthy baby girl weighing 2970 g was born with an Apgar score of 8/9. The mother and child in overall good health were discharged. Ten months after the delivery, there was no clinical evidence of recurrence. Conclusions. We believe that it is appropriate to perform radical abdominal trachelectomy in the early second trimester with preserving uterine arteries, although it is a technically challenging approach. It may be possible that radical abdominal trachelectomy during pregnancy can help women avoid the triple losses of a desired pregnancy, fertility, and motherhood.

RESUMEN

OBJECTIVE: Obstetric complications occur more frequently in pregnancies after in vitro fertilization (IVF). We attempted to determine the correlation between subchorionic hematoma and IVF pregnancies. STUDY DESIGN: We analyzed 194 pregnancies achieved by infertility treatment between January 2008 and February 2012 at our hospital. Among these, 67 were achieved by IVF and 127 by non-IVF approaches. We compared the frequency of subchorionic hematoma between the groups and examined the risk factors for subchorionic hematoma in the IVF group. RESULTS: No significant differences regarding age and the number of uterine surgery were observed between the groups. The duration of infertility was longer, parity and the rate of luteal support were higher in the IVF group compared with that in the non-IVF group. The frequency of subchorionic hematoma was significantly higher in the IVF group (22.4%) than that in the non-IVF group (11%) (P=0.035). Univariate analysis in the IVF group demonstrated that frozen-thawed embryo transfer (OR, 6.18; 95% CI, 1.7-22.4), parity≥1 (OR, 3.67; 95% CI, 1.0-13.2) and blastocyst transfer (OR, 3.75; 95% CI, 1.1-13.3) were risk factors for the subchorionic hematoma. CONCLUSION: The frequency of subchorionic hematoma is high in IVF pregnancies, and frozen-thawed embryo transfer, parity≥1, and blastocyst transfer may contribute to subchorionic hematoma onset.

RESUMEN

OBJECTIVES: Increased incidence of preterm birth, pregnancy-induced hypertension (PIH) and small-for-gestational-age (SGA) babies have been reported in women with endometriosis, but the study populations included women in whom a definitive diagnosis was not attainable, and women who conceived via in vitro fertilization/embryo transfer (IVF/ET), which, in itself, is a risk factor for adverse pregnancy outcome. Thus there is a lack of consensus on the effects of endometriosis on pregnancy outcome. This study compared the pregnancy outcomes of women with or without a definitive diagnosis of endometriosis on laparoscopy. STUDY DESIGN: Retrospective comparison of pregnancy outcomes of 108 women who underwent managed delivery of pregnancies established after laparoscopic investigation of infertility. Women with factors known to affect pregnancy outcome, such as age ≥41 years, conception via IVF/ET and multiple births, were excluded. Forty-nine of the study participants had endometriosis (En+ group) and 59 participants did not have endometriosis (En- group). RESULTS: There were no significant differences in mean (±standard deviation) age (33±3.8 vs 33.6±4.1 years), history of miscarriage, history of preterm birth and history of PIH between the two groups. Ovulation induction was used for infertility treatment in 26.5% of the En+ group and 30.5% of the En- group, and artificial insemination was used in 30.6% of the En+ group and 32.2% of the En- group. Regarding pregnancy outcomes, no significant differences in miscarriage (18.4% vs 18.6%), subchorionic haematoma (5.0% vs 2.1%), preterm birth (7.5% vs 8.3%), PIH (15.0% vs 12.5%), caesarean section (32.5% vs 22.9%), gestational age at delivery (38.9±1.5 vs 38.8±1.7 weeks), birth weight (3013.3±480 vs 2934.5±639.5g) and SGA babies (2.5% vs 2.1%) were found between the En+ and En- groups. Placental abruption did not occur in either group. One neonate had trisomy 21 in the En+ group, and one woman had gestational diabetes in the En- group. CONCLUSION: Endometriosis may not affect pregnancy outcome, but there is a need for a large prospective study.

RESUMEN

There have been very few reports on the outcomes of in vitro fertilization and embryo transfer (IVF-ET) in women with stage I/II endometriosis. The objective of this study was to investigate IVF-ET outcomes in women with early-stage endometriosis. We enrolled 35 women less than 40 years with unexplained infertility who underwent IVF-ET into the study. We compared 18 women with stage I/II endometriosis according to the revised American Society for Reproductive Medicine classification for endometriosis, who underwent 39 IVF-ET cycles (En (+) group) with 17 women without endometriosis who underwent 41 IVF-ET cycles (En (-) group). Higher requirements of total gonadotropin, a lower percentage of high-quality embryos of all fertilized eggs (9.0% vs. 16.3%), a relatively lower pregnancy rate (33.3% vs. 41.5%), and a lower live birth rate (25.6% vs. 34.1%) were observed in the En (+) group. Although no significant effect on IVF-ET outcome was observed, ovarian response may be decreased in women with stage I/II endometriosis. Considering the decreased number of high-quality embryos in the En (+) group, stage I/II endometriosis may have detrimental effects on embryo quality.

RESUMEN

A 31-year-old woman complained of dyspnea and orthopnea at 38 weeks of gestation. A grade 3/6 pansystolic murmur was heard, and echocardiography revealed severe mitral regurgitation with a hyperechoic obstacle on the posterior mitral valve leaflet, consistent with a diagnosis of acute heart failure due to a ruptured chordae tendineae or an infectious endocarditis. An emergency cesarean section was performed under general anesthesia. A male infant was born weighing 2928 g with Apgar scores of 7 and 8 at 1 and 5 min, respectively. The patient was managed in the intensive care unit and underwent open-heart surgery for mitral valve repair on postpartum day 3. The two chordal tendineae appeared torn and frail, and a mitral annuloplasty was performed. No finding of infectious endocarditis was observed. Because it is a dramatic and life-threatening clinical situation, proper diagnosis and treatment in the intensive care unit assure a good outcome for both mother and fetus.

RESUMEN

PURPOSE: We aimed to compare the efficacy of a gonadotropin-releasing hormone (GnRH) antagonist protocol and a GnRH agonist long protocol used in the first in vitro fertilization-embryo transfer (IVF-ET) cycle in an unspecified population of infertile couples. METHODS: Fifty and 34 patients were treated with a GnRH agonist long protocol (agonist group) and GnRH antagonist protocol (antagonist group), respectively, in the first treatment cycle. The primary and secondary outcome measures were cumulative live birth rates after fresh and cryopreserved-thawed ETs and incidence of grades II and III ovarian hyperstimulation syndrome (OHSS), respectively. RESULTS: No significant differences were observed in clinical pregnancy rates (38.0 vs. 32.4%) and live birth rates (22.0 vs. 23.5%), which included both fresh and cryopreserved-thawed ETs, between the 2 groups. However, the incidence of grade III OHSS was significantly lower with the GnRH antagonist protocol than the GnRH agonist long protocol. CONCLUSIONS: Used in the first IVF-ET cycle in an unspecified population of infertile patients, the GnRH antagonist protocol showed the same clinical outcome as the GnRH agonist long protocol.
